Good evening this sounds like the oven is in auto mode.
Turn the power to the oven off for 5 mins, then hold down the two most left buttons on the control panel, as you turn the oven back on.
Please let me know if the display is showing an A, if it is, can you tell me what icons are above which button and what the model of oven you have is (since some have slightly different layout of buttons).
Ok please turn the power off hold down the first to button while turning it back on then press and release the 5th button, while stil holding down the first two. If this fails repeat the process but this time press and release the 4th button.
In essence we need to disable the auto timer.
If you can find the model number it removes some of the guess work from the combinations required.
Good morning do you still require assistance?
I havent heard back from you in a while, do you still require assistance?
